Well, to get started-
What thermostat did you have?
What is the new thermostat you installed?
How is it wired?
Did you turn off the furnace before installation?
Does the furnace have 24V off the board?
Is there 24V at the thermostat?
Is there an active call for heat?

it's probably cracked and this is a waste of time.
